Blockchain is a technology which digitally stores individual pieces of information (blocks) which are connected to one another. The linked blocks resemble a long chain which cannot be modified or stolen without detection. This public ledger is a record of transactions, which can be anything from money, goods or secure data.

The Many Applications of Blockchain Methods

Blockchain technology can be used in a variety of activities and assets, including:

Cryptocurrencies–  A digital currency is issued in pre-set quantities and according to stable programs. According to the crypto portal Inside Bitcoins, a blockchain is the most reliable way to ensure that this happens. For this reason, a blockchain-based platform can issue its own virtual coins, producing them in an established number.

Smart Contracts–  Contracts with information which contain their terms of executions can be stored on the blockchain. These contracts then self-execute themselves based on information they collect over time, without any input from signing parties.

This enables businesses and individuals to enter into agreements having the certainty that they will be enforced in a non-biased way. This is particularly useful for industries that produce virtual goods, where contracts between content creators and brands are difficult to enforce.

Quality Records- Digital transactions necessitate clear, accurate, retrievable records of participants’ assets, as well as the medium of transfer for those assets. Blockchain is the technology which can create and ensure that those records are protected.

Not only are blockchains resilient to external interfering and theft, but because they are decentralized, they can be accessed quickly from a variety of locations. This facilitates the trading process of cryptocurrencies, virtual goods, and a number of other products on a global level.

How Blockchain Will Change the World

Banking and Payments

As blockchain lets anyone exchange money faster, more efficiently and more securely, it is no surprise that banks and remittance businesses will be working on adopting blockchain technology to improve their transactions. 

Internet of Things

The Internet of Things (IoT) has expanded its use to a variety of sectors, such as automobiles, home appliances, and even constructions, embedding them with software, network connectivity, and sensors.

However, because these devices run from a central location which manages communications, this can allow malevolent parties to gain access to your IoT devices. Kamil Przeorski, an expert in Bitcoin and Ethereum abilities, blockchain can be a potential solution to these critical security issues because it decentralizes all of the information and data. As a result, blockchain will have more implementations as IoT capabilities increase.


As all data is verified and encrypted on a blockchain using advanced cryptography, this makes it resilient to unauthorized alterations and hacks. Centralized servers are prone to data loss, corruption, human error, and hacking.

There have been many firms that have been hacked and lost their data, such as Verizon and Target. Blockchain’s decentralized and distributed system would allow for the data stored in the cloud to be more robust and protected against attacks.


Blockchains can enable two or more parties to communicate faster, safer and more consistently. Automated or digital communication which uses pre-built algorithms is already being implemented at scale in some industries. Such examples are emails, system alerts and call notifications. 

Matt Peterson, co-founder of Jive Communications stated that while a lot of communication is currently automated, it is usually non-critical and asynchronous.

He specified that “Blockchains can shift the playing field to allow authorized, bi-directional communications and transactions that occur more freely in an automated environment and produce an immutable record of communication.” To summarize, blockchain will be able to significantly improve the safety and reliability of our communications.

Rentals and Ride-sharing

Blockchain can generate decentralized peer-to-peer ride-sharing apps, such as Uber, and allow car owners to automatically pay for things like parking, tolls, and fuel. The technology can also be applied with renting proprieties, as smart contracts self- execute and cannot be modified once they have been established.


Complicated bureaucracy and political corruption- what do they have to do with blockchain? Well, this technology can help reduce bureaucracy and increase security, efficiency, and transparency. Welfare and unemployment benefits could be verified and distributed more easily without having to rely on hard-to–trace paperwork or slow systems. With elections, the votes can be counted and verified for legitimacy.

Crowdfunding and Donating to Charities

When donating to a charitable cause, you do not know exactly what percentage of your donation will actually be given or used in helping the cause. Blockchains can ensure that the funds are allocated where they are supposed to go.

By using smart contracts and online reputation systems, donors will be allowed to see where their donations go through the use of a secure and transparent ledger.


Blockchain can be used to record sensitive information and make a decentralized database. This feature can be used to store the private patient data that hospitals collect on a secure platform which can be accessed by doctors from everywhere.

In the future, hospitals and other healthcare organizations could create centralized and secure databases based on the blockchain, using them to store medical records and share them only with authorized doctors and patients.


While blockchain is still in its initial phases, the possibilities for innovation are endless. There are plenty more industries which will be affected by this technology, such as retail, energy management, music and art, supply chain management, insurance, and many others.
